LG's green home

LAS VEGAS--At the Consumer Electronics Show, LG showed off a line of smart appliances capable of connecting to a home network and smart meter. But it's vision for the smart, greener home is much bigger, as seen here. It encompasses solar panels, a ground-source heat pump, home batteries, efficient lighting and electronics, and even electric car charging.

Internet refrigerator redux

LG's smart appliances have touch-screen displays. The company says that being connected to the Internet would allow consumers to download pre-programmed wash cycles or recipes and keep track of food in the refrigerator.

Efficient washing drum

LG also touted some of the technology inside its appliances to make them more energy efficient. The drum inside its washing machine does not use a belt as typical washers do, making it vibrate less and more efficient.
